Question

Channels that open and close in response to a specific chemical stimulus:

• A. Leakage channels
• B. Ligand gated channels
• C. Mechanical gated channels
• D. Voltage gated channels

Answer 1

The correct option is B Ligand gated channels

Ligand gated channels open and close in response to a specific chemical stimulus.
Gates of leakage channels randomly alternate between open and closed positions.
Mechanical gated channels open or close in response to mechanical stimulation.
Voltage gated channels open and close in response to a change in the membrane potential.
